SELF-HEATING SAD-IRON.

SPECIFIGATIQN form-ing part of Letters Patent No. 546,656, dated September 24, 1895.

Application filed June 17, 1895.

To all whom it may concern: y

Ie it known that JOHN M. DOEHRER, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Self-Heatlng Sad-Irons, of which the following is a specification.

My invention relates to an improvement in self-heating sad-irons; and theinvention con- `sxsts in the details of construction set forth 1n the following specification and claims.

To enable others to understand my invention, reference is had to the accompanying drawings, in which- Figure 1 represents a side elevation of my improved iron closed and ready for use. Fig'. 2 is a centralsectional View of the burner and the rear supporting-standard for the handlereservoir, which latter is shown broken. Fig. 3 is a side elevation of the iron with the handle and cover thrown back. Fig. 4 is a detail perspective viewof the perforated shield placed within the body of the iron and partially surrounding the torch or burner, so as to prevent the flame therefrom passing through the large holes in the sides of the iron-body. Fig. 5 is a detail perspective view of the damespreader and perforated air-shield to protect the flame when the iron is in operation.

Its construction and operation are as follows: l represents the iron-body, which is, of course, hollow, and the sides pierced with the large holes la for the admission of air to the interior of the iron. 2 is the handle, which, as shown at Fig. 2, has the hollow interior 2a, which serves the purpose of a reservoir. The thumb-screw 3 is removed for the purpose of filling the reservoir and is firmly seated in such handle, so as to effectually prevent evaporation.

The rear standard 4 is integrally formed with the reservoir-handle (see Fig. 2) and has the passage-way 4a, leading from such reservoir to the chamber 5, which chamber is packed full of cotton waste 6 or other like material that will check the flow of the liquid, permitting nothing but the vapor to pass through to the small outlet 7 in the forward end of said chamber, through which outlet the vapor passes, and at which point it is ignited,

Serial No.552,932| (No modell tongue will admit sufficient air through the perforations l0a for combustion, but will prevent a flow sufficient to extinguish the flame r,when the iron is being manipulated backward and forward during the operation of ironing.

11, Fig. 2, is an annular cup-like depression or recess at the base of the burner to hold suflicient liquid, which, as a preliminary step in starting the flame, is first ignited, so as to Warm up the surrounding metal and chamber and convert the vapor into gas.

12 is a cover formed integral with the two supports 4 and 13,'and overlying this coyeris the thin metal shield 14 to protect the operators hand from the direct heat of the iron. The whole upper part of the iron is pivotally supported upon the pin 15, passing through the rear of the iron-body. The handle portion of the iron is locked to the body by means of the turn-bolt 16, whose lower projection 16L is adapted to engage with the ledge 1c of the iron-body l.

17, Figs. 1, 3, and 4, is a perforated sheetmetal shield bent` in the form shown more fully at Fig. 4. rlhis shield is placed within the hollow iron-body l and will rest on the bottom-thereof, so that the two sides and end of such shield are interposed between the burner and sides and front end of the iron. This shield will cut o the liame,'so that it cannot pass through the holes 1u of the iron when said iron is being rapidly manipulated back and forth during the operation of iron ing. It is immaterial, however, whether the shield comes in contact with the inner walls of the sad-iron or is placed a short distance therefrom, the result being the same in either case.

IOC

To operate the iron,the reservoir is first filled by removingtheplug 3. Then by means of the valve-screw 4J sufficient liquid, which may be either naphtha,gasoline, or other like volatile fluid, is allowed to fiow through the channel-way et to the packing-chamber 5. Then the cover is tipped back into a vertical position, and a small quantity is then poured into the annular depression or recess ll. This recess will hold a sufficient quantity of the liquid so that, when ignited, it will burn long enough to heat the surrounding metal sufficient to vaporize the Huid and cause the vapor escaping through the small outlet 7 also to ignite, whereupon the cover is closed and fastened and the iron is soon heated sufficient for use, the spreader S serving, as before mentioned, to direct the flame toward the loottom of the iron, the reservoir 2 being capable of holding sufficient liquid to last for several hours. If, however, it should become necessary to fill the reservoir before the ironing is completed, the flame is extinguished and the reservoir refilled, in which case it will not be necessary to put any fluid in the annular recess ll, as there will be heat enough already developed, so that the fiame may be started by the application of a match at the outlet 7.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The improvement in sad irons of the character described, comprising in combination, the liquid reservoir handle 2 and means for filling the same; standard 4 havingapassageway therethrough for the liquid and a regulating valve screw therefor; said passageway terminating at a chamber filled with packing having an outlet for the vapor and at which point it is ignited, combined with a downwardly projecting spreader to direct the flame against the bottom of the sad iron; a perforated shield within said spreader to break the force of air and thus protect the flame; the hollow sad iron to which the handle portion is pivoted; holes in the sides of said iron for the admission of air; a cover for said iron integral with rear standard; and means for locking the cover to the iron, as set forth.

2. In a sad iron of the character described, comprising in combination the handle reservoir hinged to the hollow sad iron; cover therefor; burner, spreader, and perforated fiame protector', as shown; and a perforated shield within the iron to prevent the flame passing through the air holes in the sides of said iron, all as described and for the purpose set forth.
